public class ERQMSessionPing
extends ERQMComponentBase

Simple component to ping the session in the background. It can do two things. The first is to execute JavaScript if the session is no longer valid. The default action is to close the window that the ping came from. The second thing it can do is to keep the session alive. This can be useful if you want the session to not time out on particular pages. It should be used with caution as it can prevent scheduled restarts if the user leaves the browser window open.
